Abstract
Exact algebraic solutions of a one-dimensional finite-chain hard-core Bose- Hubbard model with nearest-neighbour interactions, which is related to a st ate-dependent nuclear pairing interaction with a nearest-state interaction approximation, are derived based on a simple algebraic approach. Further ex tensions to arbitrary spin cases and the corresponding Fermi-Hubbard model are also presented.
